Drying Kinetics in Solar Drying
, 2017 From ancient times foods such as fruit, vegetables, meat or fish were dried by direct sunlight. The use of the sun as energy source is advantageous from the economic as well as environmental points of view. However, this procedure has many disadvantages concerning the efficiency and product safety and quality.

Drying is the oldest preservation technique of agricultural products, and sun drying is still widely used for preservation of agricultural products in the tropics and subtropics. Previous efforts on solar drying of cereal grains, fruits, vegetables, spices, medicinal plants, and fish are critically examined.

ABSTRACT Mass losses and low quality are the most serious disadvantages of traditional grape drying methods. For the production of high quality raisins an increase in the drying rate is required and the grapes should be protected from rain, dust and insects during drying.

ABSTRACT Importance of Solar Drying is increasing worldwide, especially in areas where the use of the abundant, renewable and clean solar energy is essentially advantageous. In the developing countries and in rural areas the traditional open-air drying methods should be substituted by the more effective and more economic solar drying technologies.

ABSTRACT The drying of Sultana seedless grapes was investigated under intermittent and continuous operating conditions in a laboratory solar installation involving a thermal storage bed and an auxiliary heater. The effect of pretreatment, and of the a i r velocity on the drying rate of the grapes at constant temperature was also studied in relation t o

Efficient solar drying techniques: a review
Environmental Science and Pollution Research, 2021In the absence of effective drying techniques, a lot of food gets wasted as there is a lack of post-harvest processes. In India, most of the agricultural produces like paddy, maize, wheat, corn, oil seeds, pulses, chillies, etc. require a temperature range of 50-80 °C for effective drying.

Abstract The heat and mass transfer analysis of grain drying for a prototype model is described and the results of a parameter survey showing the effects of various system parameters on drying time are presented. The unique feature of the prototype considered here is that the dryer unit itself serves partly as a solar collector.

Abstract Industrial drying may prove to be an economical application of solar energy when the process utilizes stored energy when sunshine is not available. A simple system has been evolved in this laboratory, wherein a reservoir and heat exchanger have been incorporated. Solar heat collection and storage is effected by thermosiphon action with water.
